“…Traffic calming measures including speed bumps, speed humps, raised crosswalks, and safety islands, among other forms, helping to control speed and regulate traffic. Erecting these various measures has been found to be quite useful in promoting road safety [93][94][95][96]. During the analysis for the current study, it was observed that the majority of crashes in the Eastern Province occurred near intersections with improper speed calming measures.…”

Road traffic crashes (RTCs) are one of the most critical public health problems worldwide. The WHO Global Status Report on Road Safety suggests that the annual fatality rate (per 100,000 people) due to RTCs in the Kingdom of Saudi Arabia (KSA) has increased from 17.4 to 27.4 over the last decade, which is an alarming situation. This paper presents an overview of RTCs in the Eastern Province, KSA, from 2009 to 2016. Key descriptive statistics for spatial and temporal distribution of crashes are presented. Statistics from the present study suggest that the year 2012 witnessed the highest number of crashes, and that the region Al-Ahsa had a significantly higher proportion of total crashes. It was concluded that the fatality rate for the province was 25.6, and the mean accident to injury ratio was 8:4. These numbers are substantially higher compared to developed countries and the neighboring Gulf states. Spatial distribution of crashes indicated that a large proportion of severe crashes occurred outside the city centers along urban highways. Logistic regression models were developed to predict crash severity. Model estimation analysis revealed that crash severity can be attributed to several significant factors including driver attributes (such as sleep, distraction, overspeeding), crash characteristics (such as sudden deviation from the lane, or collisions with other moving vehicles, road fences, pedestrians, or motorcyclists), and rainy weather conditions. After critical analysis of existing safety and infrastructure situations, various suitable crash prevention and mitigation strategies, for example, traffic enforcement, traffic calming measures, safety education programs, and coordination of key stakeholders, have been proposed.

“…The speed humps are raised obstruction installed over the highways pavement across the whole lanes [13]. Speed humps have the ability to reduce the injury accidents about 41% according to Jateikienė, et al [14]. Similar findings were obtained by Čygaitė [15] who examined the effect of speed humps in Lithuania.…”

Traffic simulation represents an effective tool for evaluating the suggested alternatives to enhance traffic conditions prior to their application in real sites. U-turn sections represent examples of the complicated sections that cannot be analyzed properly without applying microsimulation approach. Recently, in Iraq, speed humps were applied in prior to the merging locations and U-turn sections to enhance traffic safety. However, the characteristics of traffic at U-turn section with the presence of speed humps have got little attention in previous literatures. This paper uses VISSIM microsimulation model to emulate traffic movements at selected U-turn sites in the cases of with and without speed humps. Three median U-turn sites have been selected where two of these sites have speed humps prior to the turning locations. Real traffic data have been obtained from these sites using video recordings to estimate specific parameters. The developed simulation models were successfully calibrated and validated with the real data. The models have been used in testing different scenarios including the effect of having different locations/ types of speed humps and finding the capacity of U-turn sections. The results showed that closer the speeds hump to the turning location is lower the time spent for merging. The time spent values are increased with the increasing of traffic speeds at humps. Higher capacity value is obtained for the site with an auxiliary lane and speeds hump compared with the other sites.

“…In some cases, those measures could be very effective, for example, one of the researches in Lithuania revealed that after installing of certain vertical traffic calming measures on the road sections, the number of fatal and injury accidents decreased by 60%, the number of people injured decreased by 63%, the number of people killed decreased by 82% (Jateikiene et al 2016). Those measures can be implemented during road design stage as well as later if the need occurs.…”

Abstract. In order to reduce accident rate on roads and streets more and more various road safety measures are being implemented each year. Nevertheless, road safety problem exists in most countries. For example, even though accident rate in Lithuania was almost halved (6372 to 3161 yearly accidents) from years 2004 to 2015, fatality rate is still quite high -8.3 per 100000 people. New regulations, approved in 2008, dictate the need of carrying out road safety audits and road safety inspections for all road and street design projects. This paper presents most common road design errors and methods of fixing those errors based on Vilnius Gediminas Technical University Road Research Institute road safety auditors' experience from years 2011 to 2016. Most common safety problems are organized and presented in groups ordered by their importance. Recommendations on how to improve road safety audit and inspection procedures in the future are formulated, as well as suggestions on improving road project design stage by taking most common flaw priority into consideration.
